At the present time, European fatigue recommendations for welded joints are established for metallic constructions (Eurocode 3), and are in preparation for handling-lifting equipment. For this reason, the French Handling-Lifting industry asked CETIM to perform a study on two types of welded joint (butt joints and cruciform joints) in two thicknesses (8 and 15 mm) to establish design S-N curves related to defined weld quality. A specific welding quality was defined with the companies in form of tables of admissible characteristics. Welded joints were then fabricated by some of the companies with the objective of obtaining weld profiles as defined in the tables, and the welds were inspected and assessed against the admissible defects. Finally, they were fatigue tested to determine the S-N curve for each type of welded joint. This paper presents the methodology used and the results obtained. These show better S-N curves than those recommended in Eurocode 3. |
